Same issue with the folowing BT headphones:

 * Plantronic BackBeat FIT.

 * Plantronic BackBeat PRO.

 * B&O Beoplay H8.

The computer has a BT USB dongle:

  Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)
  CSR8510 A10
  USB ID = 0a12:0001

The following procedure solved the problem for us:

 1. Purge Ubuntu pulseaudio packages and conf files. Backup and purge
    pulseaudio user conf files too.

 2. Install the corresponding packages from Debian testing (June 2016).
    See attached script (get-pulseaudio8-debian-amd64.sh).

 3. Restart.

 4. A2DP profile should now work as expected with the default
    bluez/pulseaudio configuration (Use pavucontrol to select A2DP
    if needed).


Since Debian Testing (June 2016) and Ubuntu 16.04 are based on the
same pulseaudio upstream version (8.0) this suggests that this
regression is maybe due to a difference in Debian and Ubuntu
packaging: either the compilation options, the default conf or the
specific patches (e.g. Ubuntu packages include more specific patches).

  [REGRESSION] bluetooth headset no longer supports a2dp

Bug description:
  Just installed 15.04 fresh from the latest ISO (beta2).

  I'm bummed to see my bluetooth headset (Bose Soundlink overear) seems
  to have regressed in functionality.

  In 14.10, I was able to set the output profile either to a2dp or
  hsp/hfp (telephony duplex).

  In 15.04, it only works in telephony duplex mode.  I can't get high
  fidelity sound playback to work at all.

  This thread seems to be related, though the workaround within did not solve 
the problem for me:
